COIN CHANGER Filed Oct. 28, 1957 /Z 'fwmfar United States Patent 2,921,591 colN CHANGER Guy M. Farrell, Chicago, lll., assignor, by mesne assignments, to Brandt Automatic Cashier Company, a corporation of Wisconsin Application october 2s, 1951, serial No. 692,613

4 claims. (c1. 13s-z) This invention relates to a coin changer such as one of the type shown in the co-.pending application of Allan E. Finke and Edgar M. Katzenberg, Serial No. 486,326, led February 7, 1955, and is directed particularly to a means for delivering change from 25, 50 or 75 as distinguished from the usual arrangement of dispensing change from $1.00.

One object of the invention is to provide a comparatively simple relay and push button arrangement that can be added to the type of machine shown in the Finke and Katzenberg application, together with an electrical operating circuit therefor, and which is operable in addition to the normal operation of depressing denomination buttons by selecting anddepressing a push button to deliver change from 25, 50 or 75 as desired.

Another object is to provide means to dispense the change from 50 for instance instead of $1.00 by merely disabling the coin ejecting mechanism for the 504il pieces in the machine and likewise to provide another means for disabling both the 50 ejector and the 25 ejector if it is desirable to dispense change from either 25 or 75 Still another object is to provide relays which are energized by selector push buttons and Vwhich are provided with switches for controlling relays that disable certain actua-ting solenoids of the coin changer, holding switches being provided to retain the relay coils energized once they are energized whereupon a subsequent coin changer operation dispenses the change from 2.5, 50 or 75 whichever is selected.

A further object is to provide a passing switch operated by any one o-f the coin ejectors for opening the circuit of one of these relays that has been energized so as to recondition the coin changer for $1.00 operation, and

ing the operator of the condition of the circuit at any time so that he knows upon operation of the coinvchanger whether it will make change from 25p, 50ct, 7 5.or $1.00.

With these and other objects in-.view, myl invention vconsists in the construction, arrangement and combination of the various parts o-f my coin changer whereby the objects above contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in detail on the accompanying drawings, wherein:

Fig. 1 is a cross-sectional View through a portion of a coin changer such as shown in the above-mentioned application to show the actuating mechanism thereof and illustrating a portion of my invention applied thereto;

Fig. 2 is a circuit diagram illustrating my invention; and

Fig. 3 is a sectional view on the line 3-3 of Fig. 1

showing a passing switch used inl connection with my invention. v .y

On the accompanying drawing I have used the reference numeral 12 to indicate a coin changer housing and adl jacent the top thereof is a coin tray 14 for stacks of coins 50) is being ejected therefrom. The reference numeral- 50 in this case indicates a 50 coin.

Ejection of the coins is effected by coin ejector bars 16 pivote'd to bell cranks 18 which are oscillatably mounted on a pivot shaft 20 supported by brackets 22. Cores 26 arev pivoted to bell cranks 18 and enter solenoids 24 which when energized draw the cores inward with respect to the solenoids and thereby rock the bell cranks.. Return springs 28 are provided for the bell cranks 18. In Fig. l1 the vertic-al solenoid 24 isshown energized and its bell crank rocked counterclockwise whereas the horizontal solenoid 24 is de-energized and its bell crank has been rocked clockwise by its return spring 28. y

In Fig.- 2 the solenoids 24 for the 50 pieces, the 25 pieces and for Others are indicated and there are also? solenoid switches 30 for the three 24(50), 24(25) and. 24(Others) vsolenoids just mentioned. The Others may;

be4 for instance two 10 solenoids, one Sq) solenoid, two 2 solenoids and one l solenoid. The last 2 solenoids dispense two pennies at a time and the arrangement just enumerated has been found in most instances the most satisfactory for substantially equal depletion of the stacks of coins in the coin tray 14. The switches 30 are closed in various combinationsto eject desired denominations of coins when making change from $1.00. v

In Fig. 2, I illustrate a wiring diagram in which the solenoids 24 and the switches 30 are connected in' an Voperating circuit, and current supply wires 46 and 48 may be suitably charged as from a rectifier 2S shown in Fig.rl. VThe lower ends of the wires 46 and 48 in Fig. 2 terminate in arrow heads to represent extension of the circuitvto the additional solenoids 24 and switches 30 included under Others The ordinary coin changer for making change from $1.00 includes the elements 24 and 30 just referred to in the circuit shown with the exception of circuit opening switches S3, S4, and S5 which are part of my invention.' I will now describe the remaining elements of my invention which are, added .to the coin changer to make it possible to selectively make change from denominations of 25, 50d: and 75.

I provide relaysL having coils R1 and R2 and manual selector switches Slf and S2 for controlling the relays.

The relay having the coil R1 Vincludes the switches S3 and S5 and a holding switch'` 32 whereas the relay'having the coil R2 includes the switch S4 and a holding switch 34. R1 when energizedopens the normally closed switches S3 andI S5 and closes the' normally open switch 32 whereas energization of R2 opens the normally closed switch S4 and closes the normally open switch 34. l y

A. pa'ssing'switch 36 is'normally closed and controls all circuits through R1 and R2' and through indicator lights L1 and L2 therefor. The holding switches 32 and 34 shunt the switches Sl and S2 whereby momentary closure of Sl or S2will eiect closure of 32 or 34 respectively, thus holding the circuit for the relay that has been energized by S1 or S2 until such time as the passing switch 36 is opened.V Resistors 44 may be included in the circuits of the relay coils R1 and R2 to reduce the current flow therethrough inasmuch as these coils do not require much current for their operation as do the solenoids 24. The indicator lights L1 `and vL2 serve to indicate that either the switch S1 or the switclrS2 has beendepressed and likewise upon extinguishment due to opening of the passing switch 36 indicate their Vsubsequent de-energization. i

Practical operation Whenithe coin changer is operated in the normalmen-V ner (for change from $1.00)1 neitherfof they manualjselector switches S1 or S2 is depressed. If it is desirable to make change from 50, however, Sz is depressed where- Patented Jan. 19,' 1960' 3 i PDQD, the relay coil R?. is, energized which closes the'holding, switch 34 so that 5 2 can be released and the coil will remain energized, and the circuit opening switch S4 is opened so that the solenoid 24(50) cannot operate. The

light 1,2 is energized to indicate that the circuiti is ready.

Referring to Fig. 3, the passing switch 36 is illustrated in detail". It hasy an upward projectionk 38 toA be actuated by a. downward projection 42 from-a passingy switch actuator in the form of a bell crank 39, longitudinal pa-rt 40 shown sectioned in- Fig. 1 and a vertical arm- 42 which is shown sectioned inl Fig. 3. The bellcrank 39 rocks on the pivot shaft and a return spr-ing 41 i'sY operableto normally rotate the passing switch actuator 39--40- 42 clockwise in Fig. 1. It has been actuated counterclockwise by the nearest belli crank 18 and this-results in the projection 42 passing the projection 38 andbending the switch 36 upwardly in Fig. 3 withoutr openingl the circuit. However, when theY projection 42 moves in the opposite direction it will' so engage the projection 38- as to openl the switch 36' in an obvious manner and thenpermit it to re-close before the actuator 39-40-42 returns to its initial position against a stop 43 under the action of the spring 41.

When the passingv switch 36 opens, the relay coil R2 and the indicator light L2'are de-energized andthe circuitl is conditioned for subsequent normalV operationthat is, making change from $1.00;

In the event that change is to be made from either orV 75 the switch S1 is manually closed for energizing the relay coil R1 which opens switches S3 and S5 inboth the and 25e solenoid circuits. Thus neither ofthe 50 or 25 coin ejectors will operate wh'en'their respective switches 30 are closed because of the normal operation ofthe coin changer-that is, the depression of i 15'' for instance if that is the sale, whereupon the solenoid' for the 10 ejector only will' operate. Likewise the 10 ejector only will operate if is 'rung up on'the coin changer for a 65 purchase from' 75 paid." VThus th'e switch S1 is used for making', change from either 2150,"

or and only two of' the selector switchess? and' S? thus need be provided toadapt a $71.00 coin changer to make change from any of 25,` 50 or 75d,

Again the passing switch 36will open uponthe return of the coin ejector or` ejectors to normal positions after de-energization.` of the relay lR1 and the, indicator light L1, thus, conditioning the, circuit for silbseqilentfLOl) operation again. From the foregoing,specificationi it Willbe obvious that I have provided a comparatively simple relay and sfelector switch `arrangement with, only three circuitfconnections (switches Si, S4 and.` 5.5). into, the normal $1.00, coin changer to adapt itu for 25d', 50 and 75` operation also.V

Therelays and switches as Well as the indicatorl lights Ll andL2 anlfthe; passingf switch 36 are relatively small so that, they can,be,mounte d, in the coin changer housing and the housing for the denomination push, button assembly that operates the coin` changer without interfering with any. of. the mechanism.,

Some, changes maybe made, in the constructionand arrangement of the parts of my coin changer without` de-V parting from the real spjrit and purpose of my invention,

and it is my intention to cover by my claims any moditied forms-ofstructure on use of: mechanical; equiyalents which may reasonably be included within their. scope.4
